Gen4 Mazda 3 Turbo Performance Lowering Springs

Putting a turbocharged engine in the GEN4 Mazda 3 was a step in the right direction for Mazda but it still misses the mark of a “hot hatch”. Well, that’s where we come in! Introducing the CorkSport Lowering Springs for 2021+ Mazda 3 Turbo. We took what we learned from the naturally aspirated Mazda 3 and applied it to the slightly heftier turbo models. This resulted in a great new ride height and improved handling to push the GEN4 closer to a hot hatch, without ruining the daily driving comfort. Read on for full details and images of the great new look!

Let’s start off with what everyone wants to know: ride height! With only one driveline & transmission option, we could really dial in the ride height for both turbo hatchback and sedan models. The CS lowering springs for the turbo models offer a similar ride height drop to the N/A models. For the turbo hatchback, this means a ride height drop of approximately 1.5” in the front and 1.8” in the rear. For the slightly heavier turbo sedan, expect a drop of 1.5” in the front and 1.9” in the rear. While the sedan is a slightly larger drop in the rear than the hatchback, it still sits level and looks great!

This ride height is low enough to look great yet not too low to cause you issues on your daily commute. We found that this ride height can clear most driveways and speed bumps no problem. On really steep driveways, taking it slow and at an angle will help you keep your front bumper safe. We haven’t really found a driveway that was an issue though! One final note: we did test our regular, non-turbo Mazda 3 lowering springs on a turbo car. While they fit, the extra weight from the turbo system had the car sitting way too low in the front & looking ugly. We would not recommend doing this!

Moving on to the next best benefit from lowering springs: handling! The CorkSport lowering springs offer some much needed sharpness to the MZ3-T. By lowering the ride height, you lower the center of gravity of the vehicle. Combining this with stiffer than OEM spring rates, body roll is reduced, which greatly helps driver confidence through the twisties. We carefully chose our upgraded spring rates to also help reduce understeer when at the limit of traction. By increasing the rear spring rate more than the front, your turbo 3 gets better turn in and more neutral handling.

The final spring rate numbers for the Mazda 3 2.5T lowering springs actually surprised us. We tested a few different spring rate combinations to find the best balance of ride and handling. Ultimately, the same spring rates as the naturally aspirated Mazda 3 won out (this was due to both cars using the same suspension design). A 3.4K front spring and a 5.9K rear spring offered a compliant ride for daily driving, yet great handling characteristics on a backroad. The OEM dampers on the turbo models are just a hair stiffer as well, so the increase in spring rate fits fantastic with no bouncy ride!

Each set of CorkSport lowering springs for Mazda 3 turbo are made specifically to fit directly in place of the OEM springs. The only small modification that is needed is to trim the bump stops to allow for correct suspension travel before the bump stop is contacted at the new lower ride height. The springs are all made from high-tensile strength spring steel. This ensures a consistently performing spring that will stand the test of time and will not settle. We finish off each spring with a powder coated red finish. We chose red instead of the typical CS blue to help the turbo models stand out and because red things are proven to go faster! We even include a spring silencer on the rear springs to prevent any noise.

That about wraps up the launch of the CorkSport Lowering Springs for Mazda 3 Turbo. Check out the product listing at the link below for more pictures. Be sure to give us a call with any questions you have, we’re happy to help!
